' SCOTLAND ArPARA'rUs FOR RECEIVING BALLS R. ROLLS or SLIVER DISCHARGED FROM A SLIVER BALLING MACHINE Application filed June 4, 1931, Serial No.

The subject of this invention is an automatic sliver roll receiveradapted for use in conjunction with a sliver balling machine ed from the balling machine. A

The roll receiver according to the invention is so contrived that each roll ejected from the balling machine, whendeposited. on the receiver, is displaced axially to vacate the i roll-receiving station and in such displacement to impart endwise movement to a series of rolls already received, so that the foremost I roll of the series is brought to a position where it may be conveniently picked up or is delivered from the receiver on to the floor. Or there may be provided in series with the receiver which receives sliver from a balling machine fitted as an adjunct to a card a transfer device serving totransfer the balls or rolls of sliver to a drawing frame, for example, the balls or rolls being transferred manually or automatically-from the receiver to the transfer device.

, Thus there may be disposed between a pair of cards a pair'of inclined chutes the high end of each of which terminates adjacent to the relative sliver receiver and the low end of which terminates beyond the front of the relative card, the arrangement being such that, as the rolls are ejected from the receiver, they are lifted manually or mechanically on to the chute down which they roll towards the drawing frame.

Each chute may serve as a magazine, in which case the rolls will be allowed to bank upthereon and move forwardly together as each front roll is removed from the'low end of the chute.

As is understood, the rolls or balls are so wound that they do not unwind while rolling down the respective chutes.

In the accompanying drawing Figs. 1 and 2 are part elevations and part sections at right angles to one another of an automatic sliver roll receiverconstruc'ted in accordance with the invention.

Referring to the draw'ing,the sliver roll receiver shown is so contrived that each roll 1 ejected from the balling machine (not shown), when deposited-on the'receiver, is

and serving to receive the rolls or balls ejectv ceiving station 2 542,170, and in Great Britain June 4, 1930.

displaced axially in the direction indicated by the arroW A (Fig. 1) to vacate the rollreceiving station 'indicatedat 2 and in such displacement to impart'endwise movement to a series of rolls alreadyreceived, so that the foremost roll 1 of the seriesis brought to a position where it maybe conveniently picked up or is delivered from the receiver on to the floor. The receiver includes spaced parallel guide members'S, 3 and 3 'extending in a direction parallel to the axis of the rail riage 5 arranged between the guide member 3 and the guide members 3, 3 and adapted to to be returned automaticallytoposition after displacement of the roll. As each roll 1 arrives at the receiving station 2 from the balling machine it sets pawl-and-racl; mechanism into operation to eifect stepwise advance movement of the carriage 5 and therewith of the roll 1. The guide member 3 is constituted by a fixed bar and the guide members 3, 3 are constituted, respectively, by a fixed plate'and by a movable plate which is adapted to be moved by the ejected roll and which is operatively connected to a reciprocating pawl-bar 7 provided with advance and reverse pawls 8, 9 engageable, respectively, with advance and reverse rackslO, 11 carried by the carriage 5.

When the ejected roll 1 arrives at the reit is sustained between the guide members 3, 3 movement of the memher 3 being accompanied by lateral shift of the pawl-bar 7 to bring about engagement of the advance pawl 8 with its rack 10 as shown best in Fig. 2.

' The pawl-bar 7 is reciprocated by mechanism including a bell-crank lever 12, 12 crank-actuated from the main shaft 13 of the balling machine. a g A While the receiver awaits reception of a roll the reverse pawl 9 reciprocatesidly over an untoothed portion 14 at one end of the reverse rack 11 and the advance pawl 8 reciprocates idly in a space 15 10, 11.

which rolls down an inclined chute 4. to I the receiving station 2, and a movable caricS y guides '27 mounted receiver.

riage 5, said .lever 17, 18 is rocked plate 3 whereby the guide plate 8 for reception of the next roll.

The carriage 5 is provided with an upstanding braclret 16 engageable with the roll 1 whereby to propel the series of rolls sustained by the guide members 3, 3 which are made of sufficient length to carry say four or five rolls.

The movable guide plate 0 is carried by.

one arm 17 of a bell-crank lever 17, 18 fulcrumed at 19 and spring 20 so that an adjustable screw-stop 21 carried by the arm 18 is maintained normally in engagement with an abutment 22. 26 denotes an adjustable screw-stop engageable bythe arm 17 whereby to limit outward .movement of said arm under the weight of the roll 1. Pivotally connected at 28 to the arm 17 is one end of a link 24 of which the other end is pivotally connected at 25 to one end of the pawl-bar 7 the other end of which is pivotally connected at 12 to the arm 12 of the bell-crank lever 12, 12 The carriage 5 is mounted on a base 5 slidably engaging on the bed-plate 28 of the T (Fig. 1) denotes the stroke of the cardistance T being the sum of a distance T travelled by the carriage before the plate 16 engages the roll 1 ejected from the balling machine, a distance T equal to the width of the roll, and a distance T represent-ing the distance travelled by the roll 1 in the advance of the carriage before the roll 1 abuts on the first roll of the series of rolls already'on the receiver. It will thus be understood that, with the reception of eachroll vby the receiver, there is imparted to the series of rolls already thereon an axial displacement equal to the width of one roll, i. e., an axial displacement equal to the distance T As will readily be understood, when the ejected roll 1 engages on its fulcrum 19 in the direction indicated by the arrow C (Fig. 2) until the arm 17 abuts on the stop-screw The movement of the arm 17 effects through the medium of the link 24 lateral shift of the pawl-bar 7 to bring about advance operation of the carriage 5 as hereinbefore eX- plained. At the end of the forwardtravel of the carriage 5, i. e., when the trailing face of the roll 1 reaches the point B, the roll overruns theguide plate 3 on to the guide and the lever 17, 18 are relieved of load, release of the lever 17, 18 being followed by its return to normal position under the actionof the spring 20 and lateral shift of the pawl-bar '7 whereby the advance pawl 8 is disengaged from its rack 10 and the reversepawl 9 is moved into engagement with its rack 11 to effect reverse movement of the carriage 5 to normal position as indicated in Fig, 1, ready .ofthe weight of a roll,
